The Arizona Cardinals have certainly had their share of ups and downs so far this season. Riding a current five-game losing streak as they hit the bye week, they're definitely trending down.

But according to ProFootballFocus.com, a couple standout defenders' efforts have not gone unnoticed.

The website put out its list of the Top 51 players to this point of the National Football League season, and two Cardinals cracked the list.

Defensive end Calais Campbell earned the 36th spot on the list for his dynamic play.

Incredibly productive on every down, he's gone from a guy who generated a lot of pressure, to a player who can (and does) do it all. Regularly commands a lot of attention from offenses, but has still managed to make 24 defensive stops and bat four passes.

Washington continues to make plays for the Cardinals even if his reckless abandon style has seen him miss 11 tackles already this year. At times has struggled in coverage but his inside linebacker leading 62 tackles and eight sacks show just how much of a playmaker he is.
